Was it posted on your site? No. We don't have any build pics or other info of the new truck on the web site like we did on the last truck. It's a shame that we can't post them for folks at EcoModder and other interested parties. But building these hyper fuel mileage Class 8 trucks is my business, not a hobby. So I hope everyone here understands.

Can you talk in general about interpreting the green curve? Sure thing. Basically if you recall that graph in your minds eye, the green curve plotted total drag. The way cool aspect of it is that it continuously scans the whole length of the vehicle (23 meters, or 76 feet) front to rear, and gives feedback exactly where the drag is lower or where it increases. And with all of those 70 million data points plotted into the CAD model, that green curve appears to be very, very accurate. Wherever there is a "blip" in that green curve, we were able to figure out exactly what was causing that anomaly from viewing the magnified CAD model. Think of that green curve as a road map, telling you exactly where to work on the vehicle to obtain a lower Cd. Or, where you have designed your vehicle very well, to obtain very low drag.
